It's hard to pick. If I must pick, I'd say Cate Blanchett (still alive) and Katharine Hepburn (no longer alive). Add on: When confirming the name spellings, I found that Cate Blanchett actually portrayed Katharine Hepburn in a movie. I didn't know that. I guess I must just like their styles. I really liked that both can/could play both dramatic and comedic roles very well.

Q: Favorite male celebrity (need not be an actor, or could be)?
